WIRE-FENCE-STRETCHING CLAMP.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application led October 16, 1909. Serial No. 522,991.

To all whom it may concern:

Be it known that I, Jon WALLACE TAYLOR, of'No. 137 Youville Square, inthe city of Montreal, Province of Quebec, Canada, have invented certainnew and useful Improvements in Wire-Fence-Stretching Clamps; and I dohereby declare that the following is a full, clear, and eXactdescription of the same.

My invention has for its object to provide an improved fence stretchingclamp which will be simple in construction and capable of being quicklyand easily applied to and removed from the fence material.

The invention may be said briefly to consist of the construction andcombination and particular arrangement of parts hereinafter describedand pointed out in the claims. For full comprehension, however of myinvention reference must be had to the accompanying drawings forming apart of this specification, in which similar reference charactersindicate the same parts and wherein- Figure 1 is a side elevation of myimproved clamp shown in connection with a fence stretching apparatus.Fig. 2 is a plan view thereof; Figs. 3 and 4 are face views of the clamptaken in opposite directions; Fig. 5 is an enlarged detail view of themeans for drawing together the clamp; and Fig. 6 is a sectional viewtaken on line A A Fig. 5.

My improved apparatus comprises a clamp to be attached to the fencematerial, a standard for sustaining the tension of the stretching meansproper while in action, and means operatively connected between theclamp and the standard whereby the clamp is drawn toward the standardthus stretching the fence material independently of the fenlce postsready to receive the fence materia The clamp consists of a pair of jawsb and c in the form of planks of a length slightly greater than thewidth of the fence material, the jaw Z) has bolted thereto a series ofhooks e adapted to engage a corresponding series of loops or eyesf'bolted to the jaw c thus forming a readily detachable hinge connectionbetween the jaws. The jaw b also carries a series of U-pins g, 'one legz' of each of which is in the form of a crank and overhangs the unhingedside edge of such jaw while the other leg 7c projects through a rigidbar or yoke m and is pivotally connected thereto by a nut n. TheseU-pins are rotatably secured to this j aw b by bearing caps 0 boltedtherethrough and through an extension of the plates upon which' thehooks e are formed and a lever p fulcrumed beneath a bearing cap s has apin 25 engaging the yoke or bar.

The loops or eyes f upon the jaw c are formed at the ends of strapswhich have their opposite ends tapered and turned back upon themselvesto form eyes loosely retaining links o adapted to be looped over thecranks e'.

The opposite ends of the jaws have bolted thereto straps 2 formed witheyes 8 carrying links 4 affording devices for the attachment of anysuitable fence stretching means. As here shown a chain 25 has itshookedends Q6 engaging the links 4, this chain passing over a pulley 31secured to the end of a chain 30 which leads from a stretching deviceindicated at the right side of Fig. 1.

In using the clamp the lever 79 is thrown to the position shown indotted lines in Fig. 4, moving the cranks z' to the position shown indotted lines in Fig. 5, thereby releasing the links o from the cranksand permitting the aws to be swung apart until the hooks e clear theeyes or loops lf. The jaws are then placed one at each side of thematerial to be clamped with the hinge members e and f in engagement andthe lever 20 thrown to the position illustrated in full lines in Fig. 3.

What I claim is as follows 1. A fence stretching clamp comprising a pairof plank-like members, a series of oscillatory devices of U-form carriedby one of the members and each having one leg in crank form; a baroperatively connected to the other leg of each of the said devices, andmeans carried by the other clamp member and including a series of linksadapted to be engaged by the said cranks, and means for reciprocatingthe bar.

2. A fence stretching clamp comprising a pair of plank-like members, aseries of oscillatory devices of U-form carried by one of the membersand each having one leg in crank form; a bar operatively connected tothe other leg of each of the said devices, and means carried by theother clamp member and including a series of links adapted to be engagedby the said cranks, and means for reciprocating the bar consisting of alever fulcrumed to the first mentioned clamp member and pivotallyconnected to the bar.

3. A' fence stretching clamp comprising a with in exerting clampingforce upon the pair of plank-like members, a plurality of said clampingmembers; and means for ophooks mounted upon one of the members, aerating the said cranks simultaneously. bar of vU-orrn embracing theother clamp- In testimony whereof, I have signed my 15 5 ing member andpresenting at opposite ends name to this specication, in the presence ofn eye ang holok,fi the eye beingi sildapted to two subscribingWitnesses.

e engage y tie rst mentione oo r a series of links engaging the lastmentioned JOB WALLACE TAYLOR" hooks, a series of cranks mounted upon theWitnesses: 10 first mentioned clamping member and adapt- WILLIAM P.MCFERT,

ed to engage the said links and coact there- FRED J. SEARS.
